When chasing your Utah Cutthroat Slam you’ll come across some level of difficulty with each species. Probably the most difficult of four to catch would be the Yellowstone Cutthroat trout. For one, they are probably the most remote. Second they live in small creeks and are very easily spooked. Last they are difficult to find as well as fish for them.
As you can see the creek isn’t very large and neither are the fish and there are few spots that you can actually find a feeding trout.
To get up to this stream you’ll head north on I-15 out of Salt Lake City. You will head north on I-84 and take the Snowville exit off of 84. From there you will head west on state road 30. You’ll basically be hugging the Utah and Idaho Border and evening cross into Idaho. After crossing into Idaho you’ll hit E Strevell Road and you will turn left onto that Road. Continue on Strevell Rd until you hit a Y and you will turn left onto 2000E. Shortly after you will turn right onto 3700S. 3700S will basically be you driving on the Utah Idaho border. From 3700 you will turn onto One Mile Road. Where you turn is private property but you will see a small bridge when you cross the river and a forest service sign that will tell you where you can fish. You can catch fish in One Mile Creek but if you continue up stream you’ll see a road turning left that isn’t marked and take you to the top of a ridge. From there you can hike down into Sawmill Canyon which has a tributary of One Mile Creek and that is where most of the success will come from
Fishing this stream becomes tight and there is quite the amount of downed trees and debris. Practice your bow and arrow cast before you get there and be very sneaky. Some fish we had to lay on our belly and have a friend spot the strike from above because the stream was so small and spooky
This time of year we were fishing with small midges and doing pretty well. Things like tungsten surveyor’s and small red darts. You’ll need to fish small flies partially because they fish are small and won’t be able to fit larger flies into their mouths
Although small, the trout are more of a challenge and have quite the amount of spunk. You’ll only have a few opportunities until they are spooked and your chances are ruined. Fish with smaller indicators that won’t land hard on the water and high stick to where your indicator is the last thing on the water. Euronymphing does well through here because of how spooking they are so if you can get some Multi colored sighter tippet from Rio that might help.
